New Gut-Brain Circuits found for Sugar and Fat Cravings

Fat, sugar, and the combination of both (chocolate) navigate a gut-brain maze. The blue path represents the sugar route, the green path signifies the fat route, and the yellow path represents the combined impact of fats and sugars. Each path leads to the brain, but the combined route has a greater impact, triggering heightened dopamine release in the reward circuits, emphasizing the synergistic effect of fat-sugar combinations on neural responses.

A new study has unraveled the internal neural wiring of separate fat and sugar craving pathways. However, combining these pathways overly triggers a desire to eat more than usual. Understanding why we overeat unhealthy foods has been a long-standing mystery...
